A. The amount of female oocytes is decreasing with the
maternal age. The cut-off value of the decline rate is around theage
35: the rate is comparative faster in the women over 35 than those under 35. AMH is a stable and
representative predictor: higher the level is, more the oocytes are.

A. The components of stimulation medication are
recombinant gonadotropins, which play the similar roles of external hormones to
support multiple follicle growth. If no medications were used, the external
hormone can only support a single follicle growth, called as the dominant
follicle, and the other subordinate follicles (15-20 varied with the
age) will degenerate in this menstrual cycle.

A. Since the medications just rescue the subordinate
follicles to become dominant, no additional stock are triggered. So the answer
is "no."

4.
Is it painful to get the injection?

A. Most injections are subcutaneous, and the injection
site are at lower hip or lower abdomen, where are not hypersensitive.

5.
Is the retrieval operation difficult?

A. Since the
introduction of sonographically guided viginal oocyte retrieval, the
double-lumen needle can go through the route without penetrating the
hypersensitive areas, and the diameter of needle is greatly reduced. The
anesthesia is recommended in the nervous cases.
